2.4 GHz

2.4 GHz is a widely used frequency band for wireless communication, particularly in Wi-Fi and Bluetooth technologies. Operating in the unlicensed ISM (Industrial, Scientific, and Medical) band, it offers strong signal range and better wall penetration compared to higher frequencies like 5 GHz. However, it is more prone to interference from household devices such as microwaves and cordless phones. Despite this, 2.4 GHz remains popular due to its broad compatibility, reliability, and ability to cover larger areas with fewer access points.
